The interest to develop bio-based building materials comes from the possibility to reduce the use of materials having higher environmental impacts.


To assess the advantage on the environmental aspect, it is necessary to develop tools that are accessible to material developers. Currently, models vary from basic principles (12 principles of green chemistry or 12 green engineering principles) to life cycle assessment (LCA). The latter is built on a solid scientific assessment of the environmental impact of products and materials considering the entire life cycle impacts from raw materials extraction to the end of life. If the first models are generic, intuitive and used in development, they remain imprecise. However, the LCA, is very precise and based on a standardized method (ISO 14000 series) but remains too complex to be used during material development. As life cycle analysis is difficult to apply early in the design process, the use of streamlined LCA is an interesting option to investigate.


We integrate the principles of chemistry and green engineering into LCA results in order to develop a streamlined LCA tool that is not only intended for an LCA specialist but also to materials developers. Moreover, different streamlined LCA methods will be applied and compared to the developed model. Studies on biobased building materials will be used.



This tool will guide the developer in their process of proposing novel ecofriendly building materials. Such tool will help in establishing empirical graphs by impact category.
